If two people pull on it in opposite directions, it stretches and remains in a new shape

Answer 1

To determine if an object has elastic properties, you would observe the following behavior:

1. Stretching and Recovery: If two people pull on the object in opposite directions and it stretches but then returns to its original size and shape when the force is removed, the object demonstrates elastic properties. This indicates that the material can deform under stress but can regain its original form.

The other scenarios you mentioned suggest that the object either does not have elastic properties (maintains shape or falls apart) or has plastic (permanent deformation) characteristics (stretches and remains in a new shape).
